Description

  The present disclosure relates to a communication device, a power distribution control device, and a power distribution control system, and particularly, for example, a communication device and a power distribution that can perform appropriate power distribution following a change in power required for each of a plurality of regions. The present invention relates to a control device and a power distribution control system.

  At present, power plants in Japan predict the demand for electric power required by ordinary households and supply electric power with a supply amount corresponding to the predicted demand. Then, based on the predicted demand for power, by adjusting the transformation ratio when power is supplied to ordinary households, etc., for example, for single-phase 100V, power is distributed at a voltage value in the range of 95V to 107V. I try to do it.

  Patent Document 1 discloses a voltage maintenance technique for maintaining the voltage value of the distributed power within a predetermined range by linking each substation.

  In recent years, smart grid technology that efficiently supplies electric power from power plants to ordinary homes has attracted attention, mainly in North America. According to this smart grid technology, by using advanced IT technology, it is possible to dynamically change the supply of power from the power plant according to the demand for power by ordinary households.

Furthermore, in connection with the problem of global warming due to CO ₂ etc., a solar power generation panel that receives sunlight to generate electricity or a storage battery that accumulates electric energy, etc., is supplemented as a power supply source in ordinary households. Attempts to utilize it are spreading throughout the world. For this reason, solar power generation panels and the like are being supplementarily used in ordinary households in Japan.

[Configuration example of power distribution control system 1]
FIG. 1 illustrates a configuration example of a power distribution control system 1 to which the present disclosure is applied.

The power distribution control system 1 supplies (distributes) necessary power to the area 21 in accordance with, for example, demand for power required in the area 21 to be distributed. The area 21 includes, for example, each of the houses 21 _{1 to} 21 _N that consumes power by using electrical appliances. Further, as the electric power supplied to each of the residences 21 _{1 to} 21 _N , single-phase 100V, single-phase 200V, three-phase 200V, and the like are used. Is doing. Therefore, it goes without saying that the following embodiments are not limited to single-phase 100V.

The power distribution control system 1 includes communication devices 41 _{1 to} 41 _N provided in the residences 21 _{1 to} 21 _N , a network 42, a power distribution control device 43, a transformer 44, and a reactive power control device 45.

The communication device 41 ₁ calculates calculation information necessary for calculating the power consumed by the electrical appliances and the like provided in the residence 21 ₁ (for example, to identify the combined impedance value of the electrical appliances and the electrical appliances). Device ID, etc.) is supplied to the power distribution control device 43 via the network.

Note that the communication devices 41 _{2 to} 41 _N are configured in the same manner as the communication device 41 _1, and thus description thereof is omitted.

The network 42 is, for example, the Internet, and connects the communication devices 41 _{1 to} 41 _N and the power distribution control device 43 to each other by wire or wireless.

The power distribution control device 43 calculates the power required in the region 21 (hereinafter referred to as demand power) based on the calculation information supplied from the communication devices 41 _{1 to} 41 _N via the network 42 and calculates the power. Depending on the result, the transformer 44 and the reactive power control device 45 are controlled.

The transformer 44 transforms the voltage of the power supplied from the power plant via the transmission line according to the control from the power distribution control device 43 at a predetermined transformation ratio (for example, transforms 6600V to 100V), and after the transformation Is supplied to each of the residences 21 _{1 to} 21 _N.

The reactive power control device 45 adjusts the amount of reactive power flowing on the transmission line according to the control from the power distribution control device 43. Here, the reactive power refers to power that is not consumed by a load such as an appliance provided in each of the residences 21 _{1 to} 21 _N , and is power that only reciprocates between the power sender side and the receiver side.

  Accordingly, reactive power is consumed as thermal energy by the resistance component of the transmission line in the process of reciprocating between the sender side and the receiver side.

The reactive power is generated by an inductance component of the transmission line and a reactance component accompanying a load such as an appliance provided in each of the residences 21 _{1 to} 21 _N , and deteriorates the power factor. Here, the power factor refers to the phase difference θ between the alternating current and the alternating voltage on the transmission line expressed as cos θ.

[First Configuration Example of Communication Device 41 _n ]
Next, FIG. 2 shows a configuration example of the communication device 41 _n provided in the residence 21 _n (n = 1, 2,..., N−1, N). Incidentally, the communication device 41 _n is connected to the installed AC power to the household 21 _n (outlet) via the AC power supply to obtain electric power from the retracted transmission lines residence within 21 _n . The communication device 41 _n operates based on the acquired power, and is connected to a device group 61 including electrical appliances and the like provided in the residence 21 _n via a power line.

The communication device 41 _n includes a power detection unit 81, an impedance calculation unit 82, a table storage unit 83, and a communication unit 84.

The power detection unit 81 is connected to the AC power source in the residence 21 _n via a power line, and the power from the AC power source together with the device group 61 is calculated in the impedance calculation unit 82 and the table storage unit 83 in the communication device 41 _n . And supplied to the communication unit 84.

The power detector 81 detects the amount of power consumption that is supplied from the AC power supply to the device group 61 is consumed, the display device provided outside the dwelling 21 _n to be displayed (not shown) or the like. Then, on the power company side, for example, once a month, the amount of power displayed on the display device is confirmed. Based on the confirmed items, the power company provides electricity to residents living in the residence 21 _n. Charges will be charged.

The impedance calculation unit 82 acquires the device ID of each electrical appliance constituting the device group 61 connected to the communication device 41 _n . Incidentally, the device ID, for example, a user, a device ID of the device group 61 connected to the communication device 41 _n, such as by input by using the operation unit (not shown) provided in the communication device 41 _n To be acquired.

In addition, the impedance calculation unit 82 reads out the impedance associated with each device ID of each electrical appliance constituting the device group 61 from the table stored in the table storage unit 83. Based on the read impedance, the impedance calculation unit 82 calculates a combined value representing the impedance of the entire device group 61 (impedance when the entire device group 61 is viewed as one load), and Supply. When only one electrical appliance is connected to the communication device 41 _n , the impedance calculation unit 82 uses the impedance read from the table stored in the table storage unit 83 as a combined value as it is as a combined value in the communication unit 84. Supply.

  By the way, the communication unit 84 may be supplied with the phase information and voltage value information of the AC power supply (for example, if the phase is single phase 100V, the phase information is single phase and the voltage value information is 100V). . Note that the phase information and voltage value information of the AC power supply are detected by, for example, the power detection unit 81 directly connected to the AC power supply and supplied to the communication unit 84.

  In this case, the communication unit 84 transmits the phase information and voltage value information of the AC power source together with the combined value to the power distribution control device 43 in FIG. Then, in the power distribution control device 43 of FIG. 5, power distribution is controlled based on the composite value from the communication unit 84 and the phase information and voltage value information of the AC power source from the communication unit 84. In this case, the communication unit 84 will be described as transmitting only the composite value to the power distribution control device 43 in FIG.

  As shown in FIG. 3, the table storage unit 83 stores (holds) in advance a table in which the product type number, item, device ID, and impedance of each electrical appliance are associated with each other. The impedance is represented by a complex number format.

  In the table held by the table storage unit 83, as shown in FIG. 3, one impedance is associated with each electrical appliance. Therefore, for example, electrical appliances having the same impedance are registered in the table held by the table storage unit 83 regardless of the operation.

  In addition, you may make it register the electrical appliance from which an impedance changes according to operation | movement to the table which the table memory | storage part 83 hold | maintains. In this case, for example, the average of the impedance that changes according to the operation of the appliance is registered as the impedance.

Here, in addition to providing a table storage unit 83 for each communication device 41 _n , a server connected to the network 42 and holding a table as shown in FIG. 3 in advance is prepared. May be. In this case, the impedance calculation unit 82 reads the table from the server connected to the network 42 and acquires the impedance of each electrical appliance constituting the device group 61.

If you have provided the server that previously holds a table as shown in FIG. 3, the communication device every 41 _n, it is not necessary to hold duplicate table as shown in FIG. 3, the table storage unit 83 Can be omitted. A plurality of servers may be provided as necessary. This also applies to the later-described other communication device 41 _n (e.g. FIG. 8 or the communication device 41 _n to be described with reference to FIG. 21).

  The communication unit 84 supplies the combined value from the impedance calculation unit 82 to the power distribution control device 43 in FIG. 5 via the network 42.

Next, the impedance transmission process performed by the communication device 41 _{n of} FIG. 2 will be described with reference to the flowchart of FIG.

In step S21, the impedance calculation unit 82 acquires the device ID of each electrical appliance constituting the device group 61 connected to the communication device 41 _n . In addition, the impedance calculation unit 82 reads out the impedance associated with each device ID of each electrical appliance constituting the device group 61 from the table stored in the table storage unit 83. Then, the impedance calculation unit 82 calculates a combined value representing the impedance of the entire device group 61 based on the read impedance, and supplies it to the communication unit 84.

  In step S <b> 22, the communication unit 84 supplies the combined value from the impedance calculation unit 82 to the power distribution control device 43 via the network 42. Thus, the impedance transmission process is completed.

As described above, according to the impedance transmission process, for example, the communication device 41 _n transmits the composite value of impedance necessary for calculating the power consumption consumed in the residence 21 _n to the power distribution control device 43. be able to.

[First Configuration Example of Power Distribution Control Device 43]
Next, FIG. 5 shows a configuration example of the power distribution control device 43 that receives the composite value from the communication device 41 _{n of} FIG.

  The power distribution control device 43 includes a communication unit 101, a demand power calculation unit 102, and a control unit 103.

The communication unit 101 receives the composite value of each communication device 41 _n supplied from the communication device 41 _n via the network 42, and supplies the power demand calculation unit 102.

The demand power calculation unit 102 calculates the power consumption for each residence 21 _n included in the region 21 based on the composite value for each communication device 41 _n from the communication unit 101. Then, the demand power calculation unit 102 supplies the calculated sum of the power consumption for each residence 21 _{n to} the control unit 103 as the demand power of the region 21. The demand power is calculated in consideration of the reactance component of the transmission line, the influence of the transformer 44, and the like. In addition, when the phase information and voltage value information of the AC power source in the residence 21 _n are also transmitted from the communication device 41 _{n of} FIG. 2, based on the phase information and voltage value information of the AC power source in the residence 21 _n . Demand power is calculated taking into account the effects of AC power. Further, the demand power is calculated in a complex number format.

  The control unit 103 controls the transformer 44 and the reactive power control device 45 based on the demand power from the demand power calculation unit 102. That is, for example, the control unit 103 holds a control table in which a transformation ratio to be set according to demand power, a reactance amount with respect to reactive power, and the like are associated with each demand power in a memory or the like (not shown). It shall be. And the control part 103 determines the transformation ratio which should be set, the reactance amount, etc. using the control table to hold | maintain based on the demand power from the demand power calculation part 102, and the determined transformation ratio, reactance amount, etc. Thus, the transformation ratio of the transformer 44 and the reactance amount of the reactive power control device 45 are controlled. Note that the control table is prepared in advance by an electric power company or the like in which an appropriate transformation ratio, reactance amount, or the like is calculated according to demand power, and the calculation result.

  By the way, for example, when the transformation ratio of the transformer 44 is a transformation ratio to be set, the control unit 103 controls only the reactive power control device 45 and sets the reactance amount of the reactive power control device 45. The reactance amount to be set can be set.

  For example, when the reactance amount of the reactive power control device 45 is the reactance amount to be set, the control unit 103 should control only the transformer 44 and set the transformation ratio of the transformer 44. It can be made to be a transformation ratio.

  That is, the control unit 103 can control at least one of the transformer 44 and the reactive power control device 45 based on the demand power from the demand power calculation unit 102. Furthermore, it goes without saying that the control unit 103 may sequentially control the transformer 44 and the reactive power control device 45 at different timings. The same applies to the control unit 103 in FIG. 11, the control unit 208 in FIG. 15, and the control unit 264 in FIG.

  Further, in FIG. 5, instead of one power distribution control device 43, for example, a first power distribution control device 43 and a second power distribution control device 43 may be provided. Then, the control unit 103 of the first power distribution control device 43 may control the transformer 44, and the control unit 103 of the second power distribution control device 43 may control the reactive power control device 45. The same can be said for the power distribution control device 43 shown in FIGS. 11, 15, and 23 described later.

  Next, a process (hereinafter referred to as a first control process) in which the power distribution control device 43 in FIG. 5 controls the transformer 44 and the reactive power control device 45 will be described with reference to the flowchart in FIG.

In step S _< b _> 41, the communication unit 101 receives a combined value for each communication device 41 _n supplied from the communication device 41 _n via the network 42, and supplies it to the demand power calculation unit 102.

In step S _< b _> 42, the demand power calculation unit 102 calculates the power consumption for each residence 21 _n included in the region 21 based on the composite value for each communication device 21 _n from the communication unit 101. Then, the demand power calculation unit 102 supplies the calculated sum of the power consumption for each residence 21 _{n to} the control unit 103 as the demand power of the region 21.

  In step S <b> 43, the control unit 103 controls the transformer 44 and the reactive power control device 45 based on the demand power from the demand power calculation unit 102. Thus, the first control process is completed.

As described above, according to the first control process, the power consumption for each residence 21 _n is calculated based on the combined value for each communication device 41 _n supplied via the network 42, and the calculated residence 21 The total power consumption for each _{n was taken as} the power demand for region 21.

For this reason, the power distribution control device 43 in FIG. 5 can calculate the demand power in the region 21 with higher accuracy than the case where the demand power is predicted (calculated) based on the past demand power history in the region 21, for example. It becomes like this. Therefore, the power distribution control device 43 in FIG. 5 controls the transformer 44 and the reactive power control device 45 based on the calculated demand power, thereby distributing power to the dwelling 21 _n at a voltage value in the range of 95V to 107V. Can be done.

  Moreover, according to the first control process, the power distribution control device 43 improves the power factor based on the active power and reactive power that constitute the calculated demand power (for example, the power factor cos θ approaches 1). To be improved). Here, the active power refers to power actually consumed in a load such as an appliance.

<2. Modification Example of First Embodiment>
In FIG. 2, the impedance calculation unit 82 synthesizes the impedance of the entire device group 61 connected to the communication device 41 _n regardless of whether or not each electrical appliance constituting the device group 61 is in an energized state. It was calculated as a value.

  However, it is the appliance that actually consumes power that is energized when the power is turned on. Therefore, the impedance calculation unit 82 may calculate the combined value only for the appliances that are in the energized state in the device group 61.

That is, for example, in the device group 61, each appliance supplies its own device ID to the impedance calculation unit 82 of the communication device 41 _n when energized. And the impedance calculation part 82 uses the apparatus ID from the electric appliance in the apparatus group 61, and the table memorize | stored in the table memory | storage part 83, and produces | generates the synthesized value only for the electric appliance in an energized state. Can be calculated.

In this case, the communication device 41 _n of FIG. 2 calculates and transmits a composite value for only the appliance that actually consumes power. Therefore, compared with the case where the composite value is calculated and transmitted for the electrical appliance connected to the communication device 41 _n , the power distribution control device 43 in FIG. 5 calculates the power consumption for each residence 21 _n more accurately. it can. As a result, it is possible to more accurately calculate the demand power in the region 21, which is the total power consumption for each residence 21 _n . For this reason, in the power distribution control apparatus 43 of FIG. 5, it becomes possible to perform more suitable control according to the demand power of the area 21. FIG.

  In addition, for example, the impedance calculation unit 82 calculates the composite value by considering which operation mode in the energized state in addition to the energized state in each electrical appliance constituting the device group 61. It may be. This is because the electric power consumption of the electric appliance differs depending on the operation mode. As the operation mode, for example, when the electrical appliance is an AV device, it has a low power consumption mode and a high power consumption mode, and when the electrical appliance is a washing machine, washing, rinsing, dehydration, etc. It has an operation mode.

That is, for example, in the appliance group 61, among the appliances, the appliance that is in the energized state supplies the mode ID representing the current operation mode to the impedance calculator 82 of the communication device 41 _n in addition to the appliance ID. It shall be.

  The impedance calculation unit 82 uses the device ID and mode ID from the electrical appliances in the device group 61 and the table stored in the table storage unit 83, and the combined value for only the electrical appliance in the energized state. Can be calculated. In this case, the table storage unit 83 stores, as shown in FIG. 7, a table in which the product type number, item, device ID, mode ID, and impedance of each electric appliance are associated with each other. It is assumed that

  In the table shown in FIG. 7, as illustrated, a plurality of mode IDs and impedances corresponding to the plurality of mode IDs are associated with the appliances operating in the plurality of operation modes. .

  However, in the table shown in FIG. 7, although not shown, one mode ID is associated with an impedance corresponding to one mode ID for an electrical appliance that operates in one operation mode. Things may be included.

  Here, the impedance calculation unit 82 may acquire the characteristics of the periodicity from the history of the device ID and the mode ID supplied from the electrical appliance having the periodicity in the operation mode, and may reflect the characteristic of the periodicity in the table storage unit 83. . Specifically, for example, when the electrical appliance is a washing machine, the time required for washing as the first operation mode is 10 minutes, the time required for rinsing as the second operation mode is 5 minutes, and the third operation If the time required for dehydration as a mode is 3 minutes, the impedance calculation unit 82 reflects these required times on the table stored in the table storage unit 83.

  In this case, for example, even if the washing machine does not supply the impedance calculation unit 82 with the mode ID indicating the operation mode after the transition according to the transition of the operation mode, the impedance calculation unit 82 stores the mode ID in the table storage unit 83. Based on the stored table, the impedance of the washing machine can be determined according to the periodicity of the washing machine.

When the operation mode is also taken into account, the communication device 41 _n in FIG. 2 calculates and transmits the combined value in consideration of the operation mode of the appliance that actually consumes power. Therefore, compared with the case where the composite value is calculated and transmitted without taking the operation mode into consideration, the power distribution control device 43 in FIG. 5 can calculate the power demand in the region 21 more accurately. For this reason, in the power distribution control apparatus 43 of FIG. 5, it becomes possible to perform more suitable control according to the demand power of the area 21. FIG.

In the first embodiment, the communication device 41 _n of FIG. 2 has been described. In addition, for example, in addition to power from a power plant, communication that supplementarily uses power obtained from a solar power generation panel or the like. An apparatus 41 _n can be employed. That is, in the first embodiment, as the communication device ₄₁₁ through 41 _n, only the communication device 41 _n of FIG. 2, can be employed only the communication device 41 _n of FIG. 8 to be described later, or both.

[Another configuration example of the communication device 41 _n according to the first embodiment]
Next, FIG. 8 shows a configuration example of a communication device 41 _n having a distributed power source such as a photovoltaic power generation panel.

The communication device 41 _n in FIG. 8 sells the power obtained from the distributed power source to the power company or uses the power obtained from the distributed power source as power for operating the device group 61. The configuration is the same as the communication device 41 _{n of} FIG.

Further, the communication device 41 _n of FIG. 8. Thus the same reference numerals for parts that are configured in the same manner as the communication device 41 _n of FIG. 2, the description thereof is omitted.

That is, the communication device 41 _n of FIG. 8 is provided with a power detection unit 121 and an impedance calculation unit 122 instead of the power detection unit 81 and the impedance calculation unit 82, and a new power conditioner 123 and a distributed power source. The communication device 41 _n is configured in the same manner as the communication device 41 _{n in} FIG.

The power detection unit 121 is connected to an AC power source in the residence 21 _n through a power line, and the power from the AC power source together with the device group 61 is stored in a table storage unit 83 in the communication device 41 _n , a communication unit 84, This is supplied to the impedance calculator 122 and the power conditioner 123.

In addition, the power detection unit 121 supplies the power from the power conditioner 123 supplied for power sale to the transmission line via the AC power supply in the residence 21 _n . This electric power is not supplied to the power plant via the transmission line, but is directly supplied to the other dwelling 21 _m (n ≠ m). The power conditioner 123 is controlled by the power distribution control device 43 when power is supplied to the power detection unit 121 for power sale. Since the control of the power conditioner 123 by the power distribution control device 43 is described in detail in FIG. 13 and the like which will be described later, description thereof is omitted here.

Further, power detection unit 121 detects the power of the electric energy or the like from the power conditioner 123, is displayed on the household 21 display device provided outside the _n (not shown) or the like. In addition to the amount of power sold, etc., the display device displays the amount of power consumed from the power plant in the residence 21 _n . On the power company side, once a month, the amount of power displayed on the display device is confirmed by humans, and based on the confirmed items, the electricity company charges the residents who live in the residence 21 _n . Billing and delivery of power selling fees by power selling are performed.

  The impedance calculation unit 122 calculates the combined value in the same manner as the impedance calculation unit 82 and supplies the combined value to the power conditioner 123. Further, the impedance calculation unit 122 corrects the calculated combined value in accordance with the control from the power conditioner 123 and supplies the corrected combined value to the communication unit 84.

  The power conditioner 123 calculates the necessary power (power consumption) in the device group 61 based on the composite value from the impedance calculation unit 122. Then, the power conditioner 123 determines whether or not the power from the distributed power supply 124 is larger than the power consumption of the device group 61, and the composite value calculated by the impedance calculation unit 122 according to the determination result. To correct.

  That is, for example, when the power conditioner 123 determines that the power from the distributed power source 124 is larger than the power consumption of the device group 61, that is, the power required from the device group 61 by the power from the distributed power source 124. When it is determined that all the power can be covered, the impedance calculation unit 122 is controlled to correct the calculated combined value to infinity (a sufficiently large value), and the communication unit 84 is supplied.

Thereby, in the power distribution control device 43 of FIG. 5, the power consumption of the device group 61 in the residence 21 _n is treated as 0, and the demand power of the area 21 is calculated.

  Further, when the power conditioner 123 determines that the power from the distributed power source 124 is not larger than the power consumption of the device group 61, that is, a part of the power consumption of the device group 61 is the power from the transmission line. If it is determined that it is necessary to cover the power, the impedance calculation unit 122 is controlled, and the calculated combined value is set to a value corresponding to the ratio between the power consumption of the device group 61 and the power obtained from the distributed power source 124. It is corrected and supplied to the communication unit 84.

Thus, the power distribution control device 43 of FIG. 5, the power consumption of the equipment group 61 in the dwelling 21 _n, the remaining power obtained by subtracting the electric power obtained from the dispersed power source 124, devices dwelling within 21 _n It is treated as the power consumption of the group 61, and the demand power of the region 21 is calculated.

  Furthermore, the power conditioner 123 converts the power from the distributed power source 124 from direct current to alternating current, and supplies the converted power to the device group 61 or the power detection unit 121.

  The distributed power source 124 is, for example, a photovoltaic power generation panel or a storage battery, and supplies power obtained by power generation to the power conditioner 123.

  In other words, the distributed power source 124 may be any device as long as it is for generating electric power as a power source.

  Specifically, for example, when the distributed power source 124 is a photovoltaic power generation panel, the power generated by the photovoltaic power generation panel is supplied to the power conditioner 123. For example, when the distributed power source 124 is a storage battery, the power generated by the power generation (discharge) of the storage battery is supplied to the power conditioner 123.

  Hereinafter, the distributed power source 124 is described as being one of a photovoltaic power generation panel or a storage battery. Note that the case where the distributed power source 124 includes a solar panel and a storage battery will be described in detail with reference to FIGS. 28 and 29.

In the communication device 41 _{n of} FIG. 8, the combined value of the device group 61 is corrected and transmitted in consideration of the power obtained from the distributed power source 124. For this reason, in the power distribution control device 43 of FIG. 5, the power consumption of the device group 61 in the residence 21 _n excluding the power consumption covered by the power obtained from the distributed power supply 124 (need to be covered by the power from the transmission line). Certain power consumption) can be calculated accurately. Therefore, the power distribution control device 43 in FIG. 5 can calculate the demand power in the region 21 (power to be supplied from the transmission line) relatively accurately.

In the first embodiment, the communication device 41 _n in FIG. 2 calculates the composite value and transmits it to the power distribution control device 43 in FIG. 5, but the composite value is calculated by the power distribution control device 43. You may make it perform. In this case, the communication device 41 _n transmits the acquired device ID to the power distribution control device 43, and the power distribution control device 43 uses the table in FIG. 3 to calculate the composite value based on the device ID from the communication device 41 _n . Will be calculated. And the power distribution control apparatus 43 will calculate the power demand of the area 21 based on the calculated composite value. Note that the communication device 41 _n that transmits the device ID to the power distribution control device 43 may or may not include a distributed power source.

In addition, for example, the communication device 41 _n transmits the acquired device ID and mode ID to the power distribution control device 43. In the power distribution control device 43, based on the device ID and the mode ID from the communication device 41 _n , FIG. The composite value may be calculated using a table.

In step S _< b _> 121, the communication unit 201 receives the device ID and the mode ID supplied from the communication device 41 _{n of} FIG. 13 via the network 42 and supplies them to the impedance calculation unit 202. Further, the communication unit 201 receives the power generation amount supplied from the communication device 41 _{n of} FIG. 13 via the network 42 and supplies it to the surplus power calculation unit 205.

In step S122, the impedance calculation unit 202 performs the same processing as the impedance calculation unit 162 in FIG. 11 based on the device ID and the mode ID from the communication unit 201, and _combines each communication device 41 _n obtained by the processing. The value is supplied to the power consumption calculation unit 204.

In step S _< b _> 123, the power consumption calculation unit 204 calculates the power consumption for each residence 21 _n based on the combined value for each communication device 41 _n from the impedance calculation unit 202, and supplies it to the surplus power calculation unit 205.

In step S124, the surplus power calculator 205, a power generation amount of each communication device 41 _n from the communication unit 201, based on the power consumption of each household 21 _n from power consumption calculating unit 204, for each dwelling 21 _n Calculate surplus power or insufficient power.

In step S125, the surplus power distribution calculating section 206, based on the excess power or under power of each household 21 _n from the surplus power calculation unit 205, distributes the dwelling 21 _n which amount corresponding power shortage power is insufficient The distribution amount of surplus power is calculated. Then, the surplus power distribution calculation unit 206 supplies the calculated distribution amount for each residence 21 _n to the control unit 208.

As a result, the control unit 208 reduces the deficiency from the dwelling 21 _n where the surplus power is excessive to the dwelling 21 _m (n ≠ m) where the deficient power is insufficient. The power conditioner 182 in the communication device 41 _n of FIG. 13 is controlled so that the power is distributed.

The surplus power distribution calculating unit 206 supplies the surplus power or the insufficient power for each residence 21 _n from the surplus power calculating unit 205 to the demand power calculating unit 207.

In step S126, the demand power calculation unit 207 uses the surplus power or the deficient power for each residence 21 _n from the surplus power distribution calculation unit 206, and is obtained by subtracting the sum of the surplus power from the sum of the deficient power. 21 is calculated and supplied to the control unit 208.

  In step S127, the control unit 208 controls the power plant (not shown) based on the demand power in the region 21 from the demand power calculation unit 207, and the power supply from the power plant to the region 21 is insufficient. Control is performed so that power is supplied at a power level higher than the total power.

  In step S128, the control unit 208 controls the transformer 44 and the reactive power control device 45 based on the demand power in the region 21 from the demand power calculation unit 207 in the same manner as the control unit 103 in FIG.

Further, based on the distribution amount for each residence 21 _n from the surplus power distribution calculation unit 206, the control unit 208 includes a power conditioner 182 in the communication device 41 _n of the residence 21 _n that has surplus power corresponding to the surplus power. The surplus power is supplied to the residence 21 _m through the power detection unit 181 and the power transmission line. As a result, surplus power is sold in the communication device 41 _n of the residence 21 _n . Thus, the third control process is finished.

As described above, according to the third control process, the power distribution control device 43 in FIG. 15 controls power distribution in consideration of surplus power in the residence 21 _n, insufficient power in the residence 21 _m, and the like. The surplus power obtained by the residence 21 _n can be utilized without waste.

Further, according to the third control process, the surplus power in the residence 21 _n is transmitted directly to the residence 21 _m without being transmitted to the power plant, so the surplus power due to the resistance component of the transmission line is reduced. Loss can be reduced.

Furthermore, when surplus power is transmitted from the residence 21 _n to the residence 21 _m , the distance that the reactive power of the surplus power reciprocates can be shortened compared to the case of transmitting power from the residence 21 _n to the power plant. Use efficiency of surplus power can be improved.

  In the first to third embodiments described above, for convenience of explanation, as shown in FIG. 1, the region where power is supplied by the control of the power distribution control device 43 of FIGS. 5, 11, and 15 is However, the present invention is not limited to only the region 21, and power can be supplied to a plurality of regions.

By the way, when surplus power is sold in the residence 21 _n , it may not be possible to sell power depending on the voltage value of the transmission line.

<5. Fourth Embodiment>
Next, referring to FIG. 17 to FIG. 20, the power distribution control device 43 in FIG. 15 divides the area where the power is supplied so that the surplus power can be sold without problems in the residences 21 _{1 to} 21 _N , for example. Or an example in the case of merging is demonstrated.

  Note that the distribution control device 43 in FIGS. 5 and 11 can also be configured to divide or merge regions in the same manner as the power distribution control device 43 in FIG. 15. Therefore, hereinafter, the power distribution control device 43 in FIG. 15 will be described as dividing or merging regions, and the description of the power distribution control device 43 in FIGS. 5 and 11 will be omitted.

FIG. 17 shows an example of the voltage value of the electric power supplied from the power plant to the houses 21 _{1 to} 21 _N via the transformer 44.

As shown in FIG. 17, for example, in the region 21, power is distributed at 6600 V from the power plant via the transmission line to the transformer 44 provided in the utility pole. Then, the transformer 44 transforms the voltage 6600V input via the transmission line so that the voltage value of the power distributed to the houses 21 _{1 to} 21 _N included in the region 21 is 95V to 107V.

That is, for example, a transformer 44, taking into account the voltage drop due to the resistance of the transmission line, the voltage 6600V input via the transmission line, household 21 ₁ transforms to a value close to 107V allowable maximum value to 21 Distribute power to _N. The voltage distributed to the houses 21 _{1 to} 21 _N is determined in advance so as to be 95 V or higher and 107 V or lower due to safety, laws, or the like.

Next, FIG. 18 shows an example of a voltage value when electric power is output from the residences 21 ₁ , 21 _N−1 , 21 _{N and the} like to the transmission line for power sale.

In FIG. 18, for example, it is assumed that the houses 21 ₁ , 21 _N-1 and 21 _N have a distributed power source such as a photovoltaic power generation panel.

In the houses 21 _{1 to} 21 _N , when power is not sold, the voltage drops due to the resistance of the power transmission line as the distance from the transformer 44 increases, as indicated by the dotted line on the upper side of FIG.

However, when selling electricity in the residences 21 ₁ , 21 _N−1 , 21 _N, etc., the voltage generally increases as shown by the solid line on the upper side of FIG.

That is, when surplus power is sold, for example, when surplus power is directly supplied from the residence 21 ₁ to the residence 21 ₂ , the voltage value of the transmission line drawn into the residence 21 ₁ is set to the residence 21. It is necessary to make it higher than the voltage value of the transmission line drawn into ₂ .

In this case, since the residence 21 ₁ exists at the end (farthest) as viewed from the transformer 44, the voltage value of the power transmission line drawn into the residence 21 ₁ is originally low. Therefore, the voltage value of the transmission line drawn into the residence 21 ₁ can be made higher than the voltage value of the transmission line drawn into the residence 21 ₂ within the range of 95V to 107V and sold without any problem. Electricity can be performed.

On the other hand, since the residence 21 _N-1 and the residence 21 _N are relatively close to the transformer 44, the voltage value of the transmission line drawn into the residence 21 _N-1 and the residence 21 _N is originally high. Therefore, in order to sell electricity, if the voltage value of the transmission line drawn into the residence 21 _N-1 or the residence 21 _N is increased, it exceeds the range of 95V to 107V. For this reason, in the residence 21 _N-1 and the residence 21 _N existing in the vicinity of the transformer 44, it may not be possible to sell power.

Therefore, in any of the residences 21 _{1 to} 21 _N , even if the voltage rises at the time of power sale, the power distribution control device can be within the range of 95V to 107V so that power can be sold without any problem. It is desirable to control at 43.

  Here, the power distribution control device 43 needs to supply power to the predetermined area with a supply amount corresponding to the power demand in the predetermined area. And the power distribution control apparatus 43 must enlarge the voltage value of the electric power on a transmission line, in order to supply more electric power, so that demand power is large.

Increasing the power voltage of the power transmission line, the power sale or the like in residential 21 _n, power voltage of the power transmission line is exceeds the 107V below the range of 95V, Therefore, it possible to carry out the power sale Can occur.

  Next, FIG. 19 shows that the power distribution control device 43 divides or merges a plurality of regions so that the power demand in the distribution target region falls within a certain range, and the voltage value increases due to power sales or the like. Even in this case, an example is shown in which power can be sold without any problem so that it is within the range of 95V to 107V.

  The power distribution control device 43 operates by setting the transformation ratio of the transformer 221 to 1: 1 and turning off the power of the reactive power control device 222 when supplying power with the regions 21 and 22 as one region. Set so that it does not. Then, the power distribution control device 43 controls the transformer 44 and the reactive power control device 45 to supply power to one region composed of the regions 21 and 22.

  In addition, when the power distribution control device 43 supplies power with the region 21 and the region 22 as separate regions, the power distribution control device 43 controls the transformer 44 and the reactive power control device 45 so that the power demand of the region 21 with respect to the region 21 is controlled. Supply power according to Furthermore, the power distribution control device 43 controls the transformer 221 and the reactive power control device 222 to supply power corresponding to the demand power in the region 22 to the region 22.

  The primary side of the transformer 221 is connected to a single-phase 100V transmission line as shown in FIG. 19, but is not limited to this. For example, the primary side of the transformer 44 Similarly, it may be connected to a 6600V transmission line.

  Next, a region setting process in which the power distribution control device 43 in FIG. 19 performs merger or division of regions according to the demand power in the region will be described with reference to the flowchart in FIG.

  This region setting process is started, for example, at a timing when the power demand changes greatly during the day. That is, for example, the region setting process is performed at a time when demand power increases greatly (for example, timing when the morning power changes to noon) or when power demand decreases greatly (for example, timing when the power demand changes from evening to midnight). It is performed several times.

  In step S141, the demand power calculation unit 207 (FIG. 15) of the power distribution control device 43 in FIG. 19 calculates demand power for each of a plurality of regions in the same manner as in step S126 of the third control process. This is supplied to the control unit 208.

  In step S142, the control unit 208 sequentially sets a plurality of areas as attention areas, and advances the processing to step S143. In step S143, the control unit 208 determines whether or not the demand power in the attention area is larger than a predetermined first threshold, and determines that the demand power in the attention area is larger than the first threshold. If so, the process proceeds to step S144.

  In step S144, the control unit 208 divides the attention area into a plurality of areas. That is, for example, when the region 21 and the region 22 are set as one attention region, the control unit 208 divides the attention region into the region 21 and the region 22. Specifically, for example, the control unit 208 changes the transformation ratio of the transformer 221 that is one-to-one, and turns on the reactive power control device 222 to operate it. Thereafter, the process proceeds from step S144 to step S147. The process of step S147 will be described later.

  In Step S143, control part 208 advances processing to Step S145, when it judges with demand power of an attention area not being larger than the 1st threshold. In step S145, the control unit 208 determines whether or not the demand power in the region of interest is a second threshold value smaller than the first threshold value and smaller than a predetermined second threshold value. When the control unit 208 determines that the demand power in the attention area is not smaller than the second threshold, that is, the demand power in the attention area is equal to or less than the first threshold and is equal to or more than the second threshold. If it is determined that, the process returns to step S142.

  In step S142, the control unit 208 newly sets a region that has not yet been set as the attention region among the plurality of regions as the attention region, proceeds to step S143, and thereafter the same processing is repeated.

  In step S145, when the control unit 208 determines that the demand power in the attention area is smaller than the second threshold, the process proceeds to step S146, and the attention area is set as a candidate for the area to be merged. Proceed to step S147.

  In step S147, the control unit 208 determines whether or not all of the plurality of regions are the attention region. If it is determined that there is a region that is not yet the attention region, the process returns to step S142, and thereafter Similar processing is repeated.

  If the control unit 208 determines in step S147 that all of the plurality of regions are the attention region, the process proceeds to step S148, and the regions that are candidates for the regions to be merged in the processing of step S146 are merged. Then, an area where the power demand is greater than or equal to the first threshold and less than or equal to the second threshold is created. The region setting process is thus completed.

  As described above, according to the region setting process, even if the voltage value on the transmission line increases due to power sale etc., each region is divided or merged so that it falls within the range of 95V to 107V. It was made to make it the area | region used as the demand electric power which is more than a 1st threshold value and below a 2nd threshold value.

  Therefore, it is possible to sell power without any problem in any region. In addition, for example, in a time zone in which the demand power is low in a plurality of regions as a whole, for example, as shown in FIG. 19, the region 21 and the region 22 are set as one large region.

  In this case, the power distribution control device 43 only needs to control the transformer 44 and the reactive power control device 45 when controlling the power distribution. For this reason, since the region 21 and the region 22 are separate regions, the transformer 221 and the reactive power control device 222 as well as the transformer 44 and the reactive power control device 45 need to be controlled. Thus, it is possible to reduce processing by control.

<6. Fifth embodiment>
In the first embodiment described above, the power distribution control device 43 calculates the demand power based on the combined value of the impedances. However, based on whether the user exists in the own residence 21 _n or not. Demand power may be calculated.

Next, referring to FIG. 21 to FIG. 24, communication device 41 _n that transmits home information indicating whether or not the user is at home, and power distribution that calculates demand power based on the home information from communication device 41 _n The power distribution control system 1 including the control device 43, the transformer 44, and the reactive power control device 45 will be described.

[Fourth Configuration Example of Communication Device 41 _n ]
FIG. 21 illustrates a configuration example of the communication device 41 _n that transmits home information.

The communication device 41 _n in FIG. 21 is provided with a new home confirmation signal transmission unit 241 and a home information reception unit 242, and a communication unit 243 in place of the communication unit 84 in FIG. Is configured in the same manner as the communication device 41 _n of FIG. Parts that are configured in the same manner are denoted by the same reference numerals, and thus description thereof will be omitted as appropriate.

The home confirmation signal transmission unit 241 outputs a home confirmation signal representing a radio signal for determining whether or not the user exists in the residence 21 _n .

It is assumed that a resident (user) who lives in the residence 21 _n always holds the portable terminal. This portable terminal determines whether or not the user is at home based on whether or not the home confirmation signal has been received with a reception intensity equal to or greater than a predetermined threshold, and displays home information indicating the determination result as shown in FIG. 21 to the home information receiving unit 242 of the communication device 41 _n .

That is, for example, when the mobile terminal determines that the received intensity of the received home confirmation signal is equal to or greater than a predetermined threshold, that is, when it is determined that the mobile terminal held by the user exists in the residence 21 _n , It is determined that it exists in the residence 21 _n . In this case, the mobile terminal generates home information indicating that the user is at home, and transmits the home information to the home information receiving unit 242.

In addition, for example, when the mobile terminal determines that the received strength of the received home confirmation signal is not equal to or higher than a predetermined threshold (or when the home confirmation signal cannot be received (when the reception strength is 0)), that is, When it is determined that the mobile terminal held by the user does not exist in the residence 21 _n , it is determined that the user does not exist in the residence 21 _n . In this case, the mobile terminal generates home information indicating that the user is not at home, and transmits the home information to the home information receiving unit 242.

  The home information receiving unit 242 receives home information from the mobile terminal and supplies it to the communication unit 243.

  The communication unit 243 performs processing similar to that of the communication unit 84 in FIG. 2 and supplies the home information from the home information receiving unit 242 to the power distribution control device 43 in FIG. 23 via the network 42.

On the other hand, the power distribution control device 43 in FIG. 23 accumulates the combined value of the device group 61 used depending on whether or not the user is at home based on the at-home information supplied via the network 42. Using the history information, a composite value for each residence 21 _n is acquired.

The power distribution control device 43 of FIG. 23 is calculated based on the combined value of the acquired each household 21 _n, to calculate the power consumption of each dwelling 21 _n, the sum of the calculated power consumption, as the power demand of the region 21 Will be.

The history information accumulated in the power distribution control device 43 in FIG. 23 is accumulated by supplying at-home information and a composite value from the communication unit 243 to the power distribution control device 43 in FIG. Before the history information is accumulated, the impedance transmission processing of FIG. 4 is performed in the communication device 41 _n of FIG. 21, and the first control processing described in FIG. 6 is performed in the power distribution control device 43 of FIG. And

For example, after the history information is accumulated in the power distribution control device 43 in FIG. 23, the communication device 41 _{n in} FIG. 21 performs a home information transmission process.

Next, the home information transmission process performed by the communication device 41 _{n of} FIG. 21 will be described with reference to the flowchart of FIG.

  In step S <b> 171, the home information receiving unit 242 receives home information from the mobile terminal held by the user and supplies the home information to the communication unit 243.

  In step S172, the communication unit 243 supplies the home information from the home information receiving unit 242 to the power distribution control device 43 in FIG. The home information transmission process is thus completed.

As described above, according to the at-home information transmission process, the communication device 41 _{n in} FIG. 21 can calculate the demand power in the power distribution control device 43 in FIG. 23 only by transmitting the at-home information. .

[Fourth Configuration Example of Power Distribution Control Device 43]
Next, FIG. 23 illustrates a configuration example of the power distribution control device 43 that calculates demand power based on the at-home information from the communication device 41 _{n of} FIG.

  The power distribution control device 43 in FIG. 23 includes a communication unit 261, a demand power calculation unit 262, a history information storage unit 263, and a control unit 264.

The communication unit 261 receives at-home information from the communication device 41 _{n of} FIG. 21 via the network 42 and supplies it to the demand power calculation unit 262.

The power demand calculation unit 262 refers to the history information stored in the history information storage unit 263 based on the at-home information for each communication device 41 _n from the communication unit 261, and the equipment provided for each residence 21 _n The combined values of the group 61 are calculated.

Specifically, for example, when the power demand calculation unit 262 obtains home information indicating that the user is at home, based on the history information, the average of the composite values transmitted when the user is at home A value, a median value, etc. are calculated as a composite value of the equipment group 61 provided in the residence 21 _n .

Further, the power demand calculation unit 262, based on the respective combined value for each dwelling 21 _n, to calculate the power consumption of each dwelling 21 _n. Then, the demand power calculation unit 262 supplies the calculated sum of power consumption for each residence 21 _{n to} the control unit 264 as the demand power of the region 21.

The history information storage unit 263 indicates, for each residence 21 _n in the region 21, a history indicating a history such as a composite value transmitted when the user is at home or a composite value transmitted when the user is absent. I remember information. The history information is created and accumulated based on, for example, at-home information from the communication device 41 _n and a composite value.

  The control unit 264 performs the same control as the control unit 103 in FIG. 5 based on the demand power from the demand power calculation unit 262.

Note that the history information storage unit 263 configures the operating state of each electrical appliance constituting the device group 61 of the residence 21 _n when the user is at home and the device group 61 of the residence 21 _n when the user is absent. You may make it memorize | store the operation state of each electric appliance to perform as historical information.

  That is, for example, the history information storage unit 263 can store the operation state (for example, whether or not the appliance is energized) in association with the device ID as history information. Further, for example, the history information storage unit 263 may store the operation state of the electrical appliance in association with the device ID and the mode ID as history information.

In this case, the power demand calculation unit 262 refers to the history information stored in the history information storage unit 263 based on the at-home information for each communication device 41 _n from the communication unit 261, and the device for each residence 21 _n. The operating state of the group 61 (and the associated device ID and mode ID) is detected.

That is, for example, the demand power calculation unit 262 detects the operation state of each electrical appliance constituting the device group 61 as the operation state of the device group 61 of the residence 21 _n . Specifically, for example, when the power demand calculation unit 262 obtains home information indicating that the user is at home, the operation state (device ID or device when the user is at home) is determined for each electrical appliance. The most accumulated history information among the IDs and the mode IDs) is detected as the operating state.

The power demand calculation unit 262, based on the detected operating state of the apparatus group 61, by using the table described with reference to FIG. 3 and 7, respectively a composite value of the device group 61 provided for each dwelling 21 _n calculate. The power demand calculation unit 262, based on the respective combined value for each dwelling 21 _n, to calculate the power consumption of each dwelling 21 _n. The demand power calculation unit 262 supplies the calculated total power consumption for each residence 21 _{n to} the control unit 264 as the demand power of the region 21.

  Next, a process (hereinafter referred to as a fourth control process) in which the power distribution control device 43 in FIG. 23 controls the transformer 44 and the reactive power control device 45 will be described with reference to the flowchart in FIG.

In step S191, the communication unit 261 receives the at-home information from the communication device 41 _{n of} FIG. 21 via the network 42 and supplies it to the demand power calculation unit 262.

In step S192, the demand power calculation unit 262 refers to the history information stored in the history information storage unit 263 based on the at-home information for each communication device 41 _n from the communication unit 261, and for each residence 21 _n . The combined value of the provided device group 61 is calculated. Further, the power demand calculation unit 262, based on the respective combined value for each dwelling 21 _n, to calculate the power consumption of each dwelling 21 _n. Then, the demand power calculation unit 262 supplies the calculated sum of power consumption for each residence 21 _{n to} the control unit 264 as the demand power of the region 21.

  In step S193, the control unit 264 performs the same control as the control unit 103 in FIG. 5 based on the demand power from the demand power calculation unit 262. This is the end of the fourth control process.

As described above, according to the fourth control process, since the demand power is calculated based on the history information, the communication device 41 _n in FIG. 21 indicates whether or not the user is at home. It is only necessary to send home information.

Note that in the fifth embodiment, the communication device 41 _n in FIG. 21 takes into account the case where history information is not accumulated in the history information storage unit 263 of the power distribution control device 43 in FIG. 82 and a table storage unit 83 are provided.

However, when history information is stored in the history information storage unit 263 in advance, the communication device 41 _n of FIG. 21 omits the impedance calculation unit 82 and the table storage unit 83, and the power supply unit 81, home confirmation The signal transmission unit 241, the home information reception unit 242, and the communication unit 243 can be used alone.

  In addition, the mobile terminal held by the user may be any terminal as long as it generates and transmits home information based on the received home confirmation signal. That is, for example, a wireless LAN communication terminal that can be connected to the Internet or the like via a wireless LAN (local area network) access point, a mobile phone, or the like can be employed.

Further, for example, when a user holds a wireless LAN communication terminal as a portable terminal, a wireless LAN access point that outputs a beacon signal as a home confirmation signal may be provided instead of the communication device 41 _n of FIG. Good.

  In this case, the wireless LAN communication terminal generates home information based on whether or not a beacon signal can be received from the wireless LAN access point with a reception intensity equal to or higher than a predetermined threshold, and transmits the home information to the wireless LAN access point ( Reply). Then, the wireless LAN access point transmits home information from the wireless LAN communication terminal to the power distribution control device 43 in FIG.

Further, for example, when a user holds a mobile phone as a mobile terminal, a femtocell (small base station) for a mobile phone that outputs a pilot signal as a home confirmation signal is provided instead of the communication device 41 _n of FIG. You may do it.

  In this case, the mobile phone generates home information based on whether or not the pilot signal can be received from the femtocell with a reception intensity equal to or higher than a predetermined threshold, and transmits the home information to the home information receiving unit 242. Then, the femtocell transmits home information from the mobile phone to the power distribution control device 43 in FIG. Here, it goes without saying that a signal accompanying location registration processing for the femtocell and location management information can be used as at-home information.

When providing a wireless LAN access point or femtocell in the residence 21 _n instead of the communication device 41 _n of FIG. 21, the history information storage unit 263 already stores history information. And

Further, for example, the mobile terminal held by the user transmits the home information via the communication device 41 _n of FIG. 21, but without passing through the communication device 41 _n of FIG. Home information may be transmitted to the power distribution control device 43. This is the same when a wireless LAN access point or femtocell is adopted instead of the communication device 41 _n of FIG.

Further, in the fifth embodiment, the power distribution control device 43 in FIG. 23 holds the history information, but the communication device 41 _{n in} FIG. 21 holds the history information corresponding to the communication device 41 _n. You may make it do.

In this case, the communication device 41 _n in FIG. 21 determines whether or not the user is at home based on the at-home information from the mobile terminal in the same manner as the demand power calculation unit 262 in FIG. Based on the history information and the like to be stored, the composite value is calculated. Then, the communication device 41 _n in FIG. 21 calculates the demand power based on the calculated composite value based on the composite value from the communication device 41 _{n in} FIG. 21 and controls power distribution (for example, in FIG. 5). To the power distribution control device 43).

Further, the communication device 41 _n of FIG. 21 can determine whether or not the user is at home based on the received at-home information as well as other determination methods.

That is, for example, in the communication device 41 _n of FIG. 21, a motion detection sensor that detects the motion of an object (for example, a user) in a predetermined range in the residence 21 _n is provided, and the motion of the object is detected by the motion detection sensor. It can be determined whether or not the user is at home depending on whether or not.

In addition, for example, in the communication device 41 _n of FIG. 21, a camera that captures a predetermined range in the residence 21 _n is provided, and the user is detected depending on whether or not the user can be detected from the captured image obtained by capturing with the camera. It may be determined whether or not is at home.

  In the fifth embodiment, the mobile terminal held by the user indicates whether or not the user is at home based on whether or not the home confirmation signal has been received with a reception intensity equal to or higher than a predetermined threshold. Although the information is generated, the method for generating the home information is not limited to this.

That is, for example, when a mobile phone is adopted as a mobile terminal held by a user, it is based on a pilot signal received from each of a femtocell provided in the residence 21 _n or a public base station installed outdoors. The home information can be generated.

Specifically, for example, when the mobile phone determines that the reception strength of the pilot signal from the femtocell provided in the residence 21 _n is the highest among the received pilot signals, the user is at home. At-home information indicating that is generated. In addition, for example, when the mobile phone determines that the reception strength of the pilot signal from the public base station is the highest among the plurality of received pilot signals, the mobile phone generates home information indicating that the user is not at home. .

Incidentally, for example, even when the user is present in the dwelling 21 _n, among the plurality of spaces constituting the dwelling 21 _n (e.g. living room or bedroom of a room or the like), depending on whether there in any space, consume power Different electrical appliances will be used.

That is, for example, when the user exists in the living room in the residence 21 _n , there is a high possibility that the electrical appliance (included in the device group 61) provided in the living room consumes power. For example, when the user exists in a bedroom in the residence 21 _n , there is a high possibility that the electrical appliance provided in the bedroom consumes power.

Therefore, in the power distribution control device 43 of FIG. 23, the power demand calculation unit 262 uses the power consumption for each residence 21 _n based on whether the user is at home in the residence 21 _n as well as the current location of the user. It is desirable to calculate

When the power demand calculation unit 262 calculates the power consumption for each residence 21 _n based also on the current location of the user, for example, when the mobile phone receives a pilot signal from a femtocell, a public base station, or the like, The current position (user's current position) is detected by using a measuring means such as a GPS (Global Positioning System) of the telephone, is included in the at-home information, and is transmitted to the power distribution control device 43 in FIG.

Then, the power distribution control device 43 in FIG. 23 refers to the history information stored in the history information storage unit 263 based on the current location of the user included in the at-home information in addition to the at-home information. The power consumption of 21 _n is calculated. In this case, for example, in the history information storage unit 263, the electrification used when the user exists in each of a plurality of spaces (for example, a bedroom, a living room, etc.) constituting the residence 21 _n. A composite value or the like for the product is stored.

  In the fifth embodiment, in the mobile terminal held by the user, the home information is generated and transmitted regardless of whether or not the user is at home, but only when the user is at home, Home information indicating that the user is at home may be generated and transmitted.

In this case, for example, when receiving the home information indicating that the user is at home from the mobile terminal, the communication device 41 _n in FIG. 21 transmits the received home information and does not receive the home information from the mobile terminal. In this case, at-home information indicating that the user is not at home is generated and transmitted.

  The same can be said for the case where the mobile terminal generates and transmits home information indicating that the user is not at home only when the user is not at home.

In the fifth embodiment, the home information is generated based on whether the mobile terminal held by the user has received the home confirmation signal from the communication device 41 _{n in} FIG. I tried to do it. However, for example, the communication device 41 _n in FIG. 21 may generate home information by itself and transmit it to the power distribution control device 43 in FIG. 23 via the network 42.

That is, for example, a mobile terminal held by a user transmits a home confirmation signal, and whether or not the communication device 41 _{n in} FIG. 21 has received a home confirmation signal from the mobile terminal with a reception intensity _equal to or higher than a predetermined threshold. The home information can be generated and transmitted to the power distribution control device 43 in FIG.

In addition, for example, as described above, the communication device 41 _n in FIG. 21 is based on a captured image output from a motion detection sensor or a camera that captures a predetermined range in the residence 21 _n . It may be determined whether or not, and based on the determination result, home information may be generated and transmitted to the power distribution control device 43 in FIG.

In the case where a femtocell or a wireless LAN access point is adopted instead of the communication device 41 _n of FIG. 21, the home information can be generated by itself.

<7. Sixth Embodiment>
By the way, in the first embodiment described above, for example, the impedance calculating unit 82 calculates the impedance of an electrical appliance or the like using a table as shown in FIG. The current flowing through and the applied voltage may be detected, and the impedance of the appliance or the like may be calculated based on the detected current and voltage.

  FIG. 25 shows an example of current and voltage.

  In FIG. 25, the horizontal axis represents time t, and the vertical axis represents a current value and a voltage value that change according to time. The alternating current changes at a predetermined frequency and is represented by a function √2 × | I | × sin (ωt−φ) indicated by a solid line. The AC voltage changes at a predetermined frequency and is represented by a function √2 × | V | × sin (ωt) indicated by a dotted line. Here, I represents current and V represents voltage. Further, ω represents an angular velocity.

  The current represented by the function √2 × | I | × sin (ωt−φ) differs from the voltage represented by the function √2 × | V | × sin (ωt) by the phase φ.

When the function shown in FIG. 25 is expressed in polar coordinates, as shown in FIG. 26, the current is expressed by the function I _m × e ^{j (ωt−φ)} , and the voltage is expressed by the function V _m × e ^jωt. Is done. J represents an imaginary number.

Based on the function I _m × e ^{j (ωt−φ)} corresponding to the detected current and the function V _m × e ^jωt corresponding to the detected voltage, the impedance calculator 82 calculates the impedance Z by the following equation (1). Is calculated.
Z = V / I = (| V | × e ^jωt ) / (| I | × e ^{j (ωt-φ)} ) = (| V | / | I |) × e ^jφ = (| V | / | I | ) × (cosφ + jsinφ) (1)

Further, when the detected current does not become a sine wave as shown in FIG. 25, the impedance calculator 82 calculates the function V _m × e ^jωt corresponding to the detected voltage as shown in FIG. One cycle is time-divided into a plurality of sections, and the impedance Z can be calculated for each of a plurality of sections obtained by time-sharing.

Next, FIG. 27 shows an ^example in which one cycle of the function V _m × e ^jωt corresponding to the voltage is time-divided into four sections, and the impedance Z is calculated for each of the four sections.

  In FIG. 27, a function √2 × | V | × sin (ωt) obtained by time-dividing one period into four sections (1), (2), (3) and (4) is shown as a function indicating voltage. It is shown. FIG. 27 shows a function (√2 / 2) × | I | × sin (ωt−φ) in the sections (1) and (3) as a function indicating the alternating current, and the section (2 ) And (4) show the function √2 × | I | × sin (ωt−φ).

  The impedance calculator 82 calculates Z1 = (| V | / | I |) × (cosφ + jsinφ) as the impedance Z in the sections (1) and (3), and the impedance in the sections (2) and (4). As Z, Z2 = (2 × | V | / | I |) × (cosφ + jsinφ) is calculated.

  Then, the impedance calculation unit 82 calculates a combined impedance value based on each impedance calculated for each section, and supplies the calculated value to the communication unit 84.

  Thus, if the impedance calculation unit 82 calculates the composite value by calculating the impedance for each section, the composite value can be accurately calculated even if the alternating current is not a clean sine wave. .

<8. Modification>
For convenience of explanation, the distributed power source 124 (FIG. 8) has been described as being one of a photovoltaic power generation panel or a storage battery.

  However, as described above, the distributed power source 124 can be, for example, a photovoltaic power generation panel 281 and a storage battery 282 as shown in FIG.

  In FIG. 28, the photovoltaic power generation panel 281 generates power by receiving light such as sunlight, and supplies power obtained by the power generation to the storage battery 282.

  The storage battery 282 stores the electric power from the solar power generation panel 281. That is, the storage battery 282 is charged with the electric power from the solar power generation panel 281.

  Further, the storage battery 282 supplies the stored power to the power conditioner 123.

  In FIG. 28, when the storage battery 282 is charged (when the battery is charged up to the maximum chargeable amount), the electric power obtained by the power generation by the solar power generation panel 281 is also shown in FIG. The power conditioner 123 may be supplied. Then, when the storage amount of the storage battery 282 becomes less than a predetermined threshold (for example, 80% of the maximum amount that can be stored), the power obtained by the power generation of the solar power generation panel 281 is supplied to the storage battery 282. May be stored.

  Next, FIG. 29 shows a configuration example of the distributed power source 124 when power is supplied to the power conditioner 123 from at least one of the photovoltaic power generation panel 281 or the storage battery 282.

  In FIG. 29, parts that are configured in the same manner as the distributed power source 124 of FIG. 28 are denoted by the same reference numerals, and therefore description thereof will be omitted as appropriate.

  That is, the distributed power source 124 of FIG. 29 is configured in the same manner as the distributed power source 124 of FIG. 28 except that a control unit 291 is newly provided between the solar power generation panel 281 and the storage battery 282.

  Note that power is supplied from the photovoltaic power generation panel 281 to the control unit 291. For example, the control unit 291 detects the amount of power stored in the storage battery 282 based on the power discharged from the storage battery 282.

  And the control part 291 determines whether the detected electrical storage amount became less than a predetermined threshold value, and when it determines with having become less than a predetermined threshold value, it supplies the electric power from the solar power generation panel 281 to the storage battery 282. Then, the storage battery 282 is charged. In this case, for example, only the storage battery 282 supplies power to the power conditioner 123.

  The supply from the solar power generation panel 281 to the storage battery 282 is performed until the storage battery 282 is charged.

  Moreover, the control part 291 supplies the electric power from the solar power generation panel 281 to the power conditioner 123, when it determines with the detected electrical storage amount not being less than a predetermined threshold value. In this case, the photovoltaic power generation panel 281 and the storage battery 282 supply power to the power conditioner 123.

  Note that the control unit 291 supplies the power from the photovoltaic power generation panel 281 to the power conditioner 123 when it is necessary to supply power to the power conditioner 123 when the storage amount of the storage battery 282 is very small. You may do it. In this case, only the electric power from the photovoltaic power generation panel 281 is supplied to the power conditioner 123.

  The distributed power source 183 in FIG. 13 can also be configured as shown in FIGS. 28 and 29 in the same manner as the distributed power source 124.

  Further, for example, in FIG. 13, when the distributed power source 183 is one of the photovoltaic power generation panel or the storage battery, the power conditioner 182 generates the amount of electric power generated from the distributed power source 124 and consumed by the load. The power generation amount of the distributed power source 183 is detected.

  However, the power conditioner 182 may detect any amount as long as it represents the amount of power generated from the distributed power source 183 and consumed by the load.

  That is, for example, when the distributed power source 183 is a storage battery, the power conditioner 182 generates the amount of power stored in the distributed power source 183 as a storage battery from the distributed power source 183 and depends on the load. You may make it detect as the electric energy of the electric power consumed.

In this case, in FIG. 13, the power generation amount storage unit 184 stores the power storage amount instead of the power generation amount, and the power storage amount stored in the power generation amount storage unit 184 is transmitted via the network 42 by the communication unit 187. It is supplied to the power distribution control device 43 in FIG. In the power distribution control device 43 of FIG. 15, the surplus power calculation unit 205 is based on the power storage amount for each communication device 41 _n from the communication unit 201 and the power consumption for each residence 21 _n from the power consumption calculation unit 204. Thus, surplus power or insufficient power for each residence 21 _n is calculated.

  This also applies to the case where the distributed power source 183 is configured as the distributed power source 124 shown in FIG. 28 in FIG. In FIG. 13, when the distributed power source 183 is configured as the distributed power source 124 shown in FIG. 29, power is supplied only from the storage battery 282 to the power conditioner 182. It is the same.

  Further, in FIG. 13, when the distributed power source 183 is configured as the distributed power source 124 illustrated in FIG. 29, power is supplied only from the solar power generation panel 281 to the power conditioner 182. Sometimes, the power generation amount is detected by the power conditioner 182.

  In FIG. 13, when the distributed power source 183 is configured as the distributed power source 124 illustrated in FIG. 29, power is supplied from the photovoltaic power generation panel 281 and the storage battery 282 to the power conditioner 182. When this is done, the power conditioner 182 detects the power generation amount of the solar power generation panel 281 and the power storage amount (or power generation amount) of the storage battery 282.

Power generation of the solar panels 281, and the storage amount of the storage battery 282 (or the power generation amount) are transmitted to the power distribution control device 43 of FIG. 15, the surplus power calculation unit 205 of FIG. 15, the surplus power of the dwelling 21 _n or Used when calculating the power shortage.

  By the way, in the case where power generation is performed by the distributed power source 124, it has been described that power generation is performed by including a photovoltaic power generation panel in the distributed power source 124. However, the power generation device that is provided as part of the distributed power source 124 and generates power is not limited to the solar power generation panel.

  In other words, for example, the power generation device may be anything as long as it is a relatively small one that can be provided in a residence. Specifically, for example, a generator that generates power by burning gas, kerosene, or the like, a generator that generates power using wind power, or the like can be employed as the power generation device.
